I whipped up a simple excel sheet for calculating Pressure ratio and mass air flow.

using Pauls estimated map for the 1752 i got this:



seems pretty safe if not ideal.
comments welcome

Looks fine, although i think your VE is optimistic.

it will be a 16 K 1100..

NA it is around that number . bit of a guess anyway

At boost, it is highly likely that the pressure in the exhaust manifold will be higher than boost that will reduce your VE.

I would use 90% VE.

It is still a good turbo selection.

okiedokie..

still into to future i fear but gathering parts.
